Applicant's summary and conclusion

Interpretation of results:
other: not irritating
Conclusions:
4-nitro-4’-aminodiphenylamine-2-sulfonic acid (CAS No:91-29-2) was considered to be not irritating to eye of rabbits.
Executive summary:

Eye irritation study was conducted in 6 rabbits for 4-nitro-4’-aminodiphenylamine-2-sulfonic acid (CAS No: 91-29-2) to assess its eye irritation efficacy in accordance with OECD guideline 405. About 100 μl of 4-nitro-4’-aminodiphenylamine-2-sulfonic acid was placed into the conjunctival sac of each rabbits and the results were recorded for 3 days. Slight reddening in only one of 6 animals was observed but this was reversible after 3 days.

Since the observed eye effects were not persisted after 3 days ,the test chemical 4-nitro-4’-aminodiphenylamine-2-sulfonic acid (CAS No:91-29-2) was considered to be not irritating to rabbits’ eye.
